A great upper, looks great December 11, 2019 : Ryan from Maine, United States   This upper is beautiful the quad rails on this are very pleasing to the eye. Upper fits snuggly to my lower, without any issues. The only problem I ran into was upon installing my Strike Industries  Sidewinder II’s I had to take a dremel and cut two of the bars off the quad rails in order to attach the front sight to it. Not a big deal. Highly recommend this upper. Was this review helpful to you?
